PROBLEM TO BE SOLVED: To provide a gas-liquid contact method by which gas-liquid contact can be performed using a gas-liquid contactor of a compact and low-power configuration.SOLUTION: The gas-liquid contact method is a circulation-type gas-liquid contact method in which a part of treatment water and target gas is discharged outside a system as treated water and treated gas while circulating, in a mixed manner, the treatment water and target gas, and a balanced amount of water before treated and gas before treated is allowed to flow into the system. The method uses a gas-liquid contactor which includes: a storage tank 1; a gas-liquid contact tower 10 which includes a water supply port at an upper portion, and a drain port and an air chamber section at a lower portion; circulating pipeline 15 which connects the storage tank with the water supply port; contact pipeline 13 which connects the storage tank with the drain port; and liquid transfer means 4 for circulating liquid between the storage tank and the gas-liquid contact tower. A cross-sectional area of the contact pipeline, a cross-sectional area of the gas-liquid contact tower in a horizontal direction, and height of the gas-liquid contact tower in a vertical direction are set within a prescribed range.

PROBLEM TO BE SOLVED: To provide a packaging container capable of easily removing dew drops and water droplets which adhere to the outer side of a container flange after purchase of a refrigerated showpiece.SOLUTION: In a packaging container 10 having a flange 11 formed at a periphery of an opening, an outer edge of the flange 11 is formed so as to hang down in an area ranging from a center part of an edge to both side parts.
Abstract:
PROBLEM TO BE SOLVED: To solve such a problem that the nitrogen substitution-multistage contact process is considered to be practical for general industrial use but the nitrogen consumption required in this process is not greatly reduced, even when the contact is made in three or more stages and the process has limitations on nitrogen consumption.SOLUTION: The gas-liquid contact process controls the nitrogen consumption close to the theoretical efficiency level in a multistage contact even in three or more stages, because the oversaturation of dissolved gas is completely avoided in each of the stages.
